REFRIGERATING APPARATUS.

Specification of Letters Patent.

Patented Nov. 19, 1918.

Application filed October 19, 1914. Serial No. 867,343.

1'0 all whom Z may concern:

Be it known that l, AUGUST P. ANnERsoN, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Refrigerating Apparatus. of which the following is a full, clear, and exact description.

The invention relates to refrigeratin apparatus in which liqueiiable gas is mec anially compressed for cooling or refrigerating purposes. i

(ine object of the invention is to provlde an improved apparatus which is entirely surrounded by the condensing Water, to increase the eliiciency of the apparatus.

A. furt her object of the invention is to provide an improved apparatus in which the receiver for the refrigerant under high pressure is .surrounded by the Water used for condensing the refrigerant agent, to increase the efficiency of the apparatus, and in which water initially passes around the re.

ceiver, next around the condenser and then around the compressor, so that the coolest water will be effective upon the receiver and. condenser.

A further object of the invention is to provide an improved apparatus in which the entire compressor, including its crank-case, are surrounded by the condensing Water,

which will absorb any of the gas that may escape` from the compressor, so that the apparatus will he rendered exceptionally" safe in use.

di. further object of the invention is to provide improved means for permitting the i escape of high-pressure refrigerant to the low-pressure side of the refrigerant line, if the pressure of the refrigerant exceeds ar safe or predetermined maximum.

A further object of the invention is to provide improved means for permitting the escape of gas which may leak into the crankcase from the compressor-cylinder.

Other objects of the invention will be apparent from the description of the apparatus hereinafter set forth.

The invention consists in the several novel features hereinafter set forth and more particularly pointed out by claims at the conclusion hereof.

In the drawings: Figure 1 is a vertical longitudinal section of an apparatus embodyi'ng the invention. Fig. 2 is a transverse section 'taken on line 2-2 of Fig. 3. Fig. 3 is a horizontal section taken on line 3 3 of Fig. 2. Fig. 4 is a section taken on line 4 4 of Fig. 3.

For convenience in connecting the inlet and outlet pipes to the apparatus, the latter is mounted upon a hase 10. A compressor, condenser and receiver are all inclosed in a case which is mounted on the base and comprises a bottom-plate 11, and a bonnet 12, which forms the sides and top of the case for containingthe condensing water and is secured to said plate by bolts 1l. The compressor comprises a crank-case 14, a pair of cylinders 15, each containing '.1 piston 16, oppositely disposed cranks 18, a pitman 19 between each pistou 16 and crank 18, and a head 20 closing the upper end of each eylinder. Franks 18 are secured to a shaft 21 which has one of its ends journaled in a head 22 at one side of the crank-case and its other end in a head 23 at the other side of said ease. These beads 22 are removably secured to the body of the crank-case by bolts 24. Cylinder-heads 20 are removably secured to the cylinder casting by bolts 25. Legs 26 on the body of the crank-caseare secured upon the bottonnplate 11 by bolts 26.`I A pipe 27, leading.;r from the cooler or refrigerator, conducts the spent refrigerant or low-pressure gas to aduct 28 which is formed in the crank-case and a cylinder casting. Pipe 27 is connected to the crank case and passes through the bottom-plate 11. A packing-box 29 is provided to prevent the escape of Water from the case. Duct, 28 communicates with a cross-duct 30 which leadsl to both cylinders 15. Each piston is provided with a suitable checkvalve 31, at its upper end, is hollow between its upper and lowerl ends, and is frmed with openings 32, so that gas in the (liylinders will be supplied to the checlr-valviesil which are normally closed by springs 33* and through which the gas will pass du ing the downstroke of the piston. A check-v lve 34, normally closed by a spring 34', permits the refrigerant under compression 1n each cylinder to pass to the high pressure side `of the refrigerant line and prevents back* flow of the high-pressure refrigeranf into the cylinders.

The crank-case contains a sup ly of lubricant 36 in which the cranks and1 lower ends of the pitmen Work, so they will lubricated and to prevent an excess of lubricant from being splashed into the cylnders, guards or wings 37 are formed in theiupper coil lfl.

A perforated lubricating ring 72 heid.

limit! 1 i between the pai-king rings 62 and lubricant is supplied to the shaft through a` pipe 73,' which is connected to boss (il adjacent ring 72, and to a reservoir Tl, containing a suppl'v of lubricant. B v piacing this lubricant chamber in the hood, as shown, the structur, of the apparatus is simplified and the necessity of making provision for pipes extending through the hood is avoided. The upper end of the reservoir 7l is provided with a filling plug 7 5.

The invention thus exemplifies a refrigerating apparatus, in which the compressor, including its cran ise, condenser coil and the receiver an, surr vxinded by the condensing water and in which the water flows successively around the receiver and condenser and the compressor, so that its greatest coolingetl'ect will be upon the refrigerant in the receiver and condenser, in which all of these parts are submerged in a body of water so that an \v gas esfaping from any portion of these, parts will he absorbed by the water and will not escape into the atmosphere. The. construction set forth is simple and can be produced at a low cost. Simple provision is made for preventing excessive pressure in-lhe higl'i-pressure side of the refrigerant-line and for the escape of ras from the crank-case.

The invention not. to be understood as restricted to thc details set forth, since lhes` may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention,
